Details and patient eligibility

About

This is a 128-week open-label study to assess the long-term safety and tolerabilty of the monoclonal antibody erenumab in migraine patients.

Full description

This was an open-label, multi-center, single arm study with flexible dosing allowing both dose adjustment and one drug holiday per patient.

The study design consisted of 3 parts:

  • Screening Epoch (0 - 2 weeks): required for all patients to assess initial eligibility. Eligible patients came from study CAMG334ADE01 (NCT03828539).
  • Open-label Treatment Epoch (128 weeks): Individual patients were treated for 128 weeks. In this open-label treatment phase, the erenumab dose could be adjusted from 70 mg to 140 mg or vice versa at the discretion of the physician at any scheduled study visit. Additionally, a voluntary single treatment interruption ('drug holiday') of up to 24 weeks (approximately six months) could be introduced after at least 12 weeks of treatment in the open-label Treatment Epoch.
  • Follow-up Epoch (4 weeks): A Follow-Up Visit 4 weeks after the last regular study visit (8 weeks after last investigational medicinal product [IMP] application) was required as part of routine safety monitoring.

Inclusion and exclusion criteria

The study population consisted of patients with a documented history of episodic (4 - 14 baseline migraine days) or chronic migraine (≥15 baseline headache days), who had been successfully randomized to clinical trial CAMG334ADE01.

  • Patient is capable of understanding the nature, significance and implications of the clinical trial.
  • Adults ≥18 years of age upon entry into screening

Key exclusion Criteria:

  • Use of a prophylactic migraine medication within five plasma clearance half-lives, or a device or procedure within one month prior to the start of the Open-label Treatment Epoch. This exclusion criteria does not apply to erenumab or topiramate administered within clinical trial CAMG334ADE01
  • Any prior exposure to (investigational) prophylactic migraine products targeting the CGRP pathway, other than erenumab.
